 Docker Python Base
 ==================
 
-A bare bones python Docker setup to support local and production development from a single ops base
+A bare bones python Docker setup to support local and production development from a single ops base. A super simple Flask app is contained in the `app/` directory for demo purposes, but this can easily be switched for any WSGI compatible application.
 
-##Steps to run
 
-1. `make all`. Note: you may need to run this as sudo, depending on how your docker install is set up, eg. `sudo make all`
+## Steps to run
 
-##Useful Docker Commands (use with care)
+For local development simply run `sudo make run-local`. Once built, the container will run the Flask demo app on http://<container_ip>:5000.
+
+To run the deploy in a production container, run `sudo make run-deploy`. Once built, the container will run the Flask demo app on http://<container_ip>.
+
+In addition to the `run` commands, `make build-local` and `make build-deploy` are available to allow building containers without running them.
+
+
+## Useful Docker Commands (use with care)
